Patented Mar. 11, 1930 PATENT OFFICE LOUIS LALANNE, 01E MARSEILLE, FRANCE SCUTTIIE PORT AND LIKE TIGHT-CLOSED WINDOW Application filed November 28, 1928, Serial No. 322,369, and in France February 15, 1928.

The object of the present invention is a means for opening and closing scuttle ports, or opening a tight closed window and shutting it again.

It is known that it has hitherto been very difficult to open scuttle ports andtight closed windows because the parts forming a tight joint with one another adhere in such a manner due to the pressure exercised on the fitting, that even after a very short time, it very often became necessary to use any suitable available object such as a lever, a key, a screw driver and so on in order to remove the pane holder from the window frame, or from the water tight seating or fitting ring respectively. The use of such makeshift tools not only involved considerable labour and trouble but was also liable to cause dislocation of and damage to the fitting ring and the pane holder. In such cases it was frequently necessary to have the scuttle port repaired, before a tight joint could again be obtained.

The principal object of the present invention is to avoid these inconveniences by providing means rendering possible the detachment, separation and moving of the pane holder from its seating or fitting ring, whilst keeping it parallel thereto, the said means consisting in a fiat collar for effecting the separation, said detaching collar being actuated either by known or new mechanical controlling means, the new controlling means being also a part of the present invention. Once the pane holder has been separated or detached from the watertight ring or its watertight fitting provided in the frame of the scuttle port, the pane holder may be further moved and the scuttle port opened progressively whilst always remaining parallel to its original position. The same means render possible the tight closure of the scuttle port by actuating them in the reverse direction.

On the drawings some embodiments of the object of the invention are shown by way of example.

Fig. 1 is a vertical section of the first embodiment showing the controlling means in the position for keeping the scuttle port tight closed.

Fig. 2 is a vertical section of the same embodiment showing said controlling means in the position for keeping the pane holder detached and rendering it possible to open the scuttle port.

Fig. 3 shows in vertical section means for moving the pane holder from the position illustrated in Fig. 2 and for returning it to the said position.

Fig.4 shows a modification of a detail of Fig. 3.

Fig. 5 is a perspective view of the movable parts of the scuttle port in the open position, parts of collars and rings being shown in dotted lines or entirely omitted (as, for example, the toothed wheels of Figures 1 and 3) for the sake of clearness.

Fig. 6 shows in vertical section the scuttle port tight closed, with a shutter up.

Fig. 7 shows on a reduced scale in dotted lines a scuttle port of known construction modified by providing the pane holder with a fiat separating collar for detaching purposes which renders it possible to keep the pane holder parallel to its original position and to the watertight ring in the frame during the opening and closing of the scuttle port.

Fig. 8 is a front Fig. 7 As shown in Fig. 1 the frame of the scuttle port consists in a ring 2 provided with a circular projecting rim or collar 8 having a continuous screw thread 4 on its outer periphery, which screw thread engages with a similar screw thread 5 provided on the inner periphery of a cylindrical crown 6. The said crown is provided at the back of the screw thread 5 with a collar 7 perpendicular to the crown 6, said collar being provided with recesses 28 and penetrating into the pane holder 8 which is ring shaped. On the outer periphery of the crown 6 are teeth 10, which are in continuous engagement with a pinion or cog wheel 11 on an axle 12. -Said axle may be provided with a handle, key or the like for turning it.

The frame 2 is provided with a watertight ring 13 of caoutchouc or like watertight material adjacent to the inner edge of the projectingrim 3.

view corresponding to A toothed wheel 15 is provided which is slidable along the outside of a guiding ring or cornice lel arranged concentrically with said circular rim 3, said guiding ring 1-1 being fixed to the frame 2. The toothed wheel 15 engages with a pinion 17. As shown in Fig. 3 a toothed cam 19 engages with teeth 18 at the rear of the toothed wheel 15, the teeth 18 being perpendicular to the teeth 16. The cam 19 carries a curved guide member 20, serving as a guide for a pin or bolt 21 (Fig. fixed to the pane holder 8.

The outermost position of the cam and the slide has been indicated in dotted lines in Fig. 3. The axle of said cam is mounted in the frame By turning the toothed wheel 15, the cam 19 is turned and the pin 21 is moved away from the wheel 15 and the frame 2.

The pane holder 8 (Figs. 1 and 5) has a flat uninterrupted collar 23 which renders it possible to detach and move away the pane holder 8 from its tightening ring 13 over its whole circumference simultaneously by means of the cylindrical crown 6. This fiat collar 23 is one of the principal features of the present invention.

A second collar 33 is arranged parallel to the flat collar 23 so as to leave an ai'mular groove 30 between the said two collars 23 and 33, and is provided with a plurality of recesses 25 thus forming projections 24. The said recesses 25 and projections 24 correspond in their position and number with projections 29 and recesses 28 of the collar 7 and serve to couple the crown 6 with the pane holder 8 during the shutting of the scuttle port.

As is shown in Fig. 6 the construction of the scuttle port as described and illustrated renders it possible to use a shutter 26 for the pane 9. Such a shutter 26 is placed on to the watertight projecting front edge 27 of the pane holder 8, and in the closed position of the scuttle port the said shutter rests with its U-shaped rim-between the watertight ring 13 and the said front edge 27 which is pressed on to the said watertight ring 13 instead of the edge 27 of the pane holder 8, whereby just the same watertight closure is obtained as is the case with the scuttle port or pane holder without the shutter 26.

The operation of opening the scuttle port may conveniently be divided into three phases:

1. The detaching of the pane holder along the whole circumference of the tightening ring 13 at the same time parallel to the rear of the frame ring-'2;

2. The entire removal of the pane holder from the frame ring 2;

3. The moving backwards of the pane holder 8 positively guided by the slides 20, 22, thus permitting of the adjustment of the position of the pane holder 8 by hand.

These different movements may be executed as follows:

Starting from the closed position of the scuttle port, as shown in Fig. 1, the axle 12 is rotated and the pinion 11 turns the crown 6, the latter turning on the collar 3 through the medium of the screw threads 5 and 1 in similar manner to a nut and thus moving away from the frame 2. The pane holder 8 is now detached from its seating or its tightening ring 13 respectively and takes up the position indicated in Fig. 2.

During this movement backwards the collar 7 causes:

1. By its connection with the flat collar 23 of the pane holder 8, its detachment from its tightening seat and simultaneously its removal from the frame 2 whilst always remaining parallel to its original position.

2. By its turning movement, the recesses 28 to come into position in front of the projections 24 of the second collar 33 of the pane holder 8.

The pane holder may now be entirely removed from the frame 2. For effecting the removal it is only necessary to turn the axle 12 (Figs. 3 and 1) so that the pinion 17 turns the toothed wheel 15. The toothed wheel 15 engages continuously through the medium of its teeth 18 with the toothed cam 19. It is preferable to arrange two such toothed cams diametrically opposite to one another on the periphery of the frame 2. These cams 19 are actuated, i. e. turned by the toothed rim 15, so that the slides 20 appertaining to said cams 19 cause the two pins 21 (Fig. to move away from the frame 2. This movement within the two slides 20 renders possible the adjustment of the opening or space, separating the pane holder 8 from the inner circumference of the frame 2. By turning the pinion 17 to a greater or a less extent a further circulation of fresh air parallel to the frame opening of the scuttle port will be obtained. The pane holder can also be easily turned around its pins 21.

A known device for fixing the pins 21 in position may be provided as shown in Fig. 5, wherein a hand wheel 31. is screwed onto one of said pins 21 so as to hold it up against one of said slides 22, the pane holder 8 being thus rendered immovable.

A casing (not shown in the drawings) may be provided in order to protect all the toothed wheels and pinions against damage from dust or ext 'aneous contact so as to ensure the reliable functioning of the device.

The modification shown in Fig. 4 is provided with a toothed wheel 15, for moving the pane holder back entirely after detachment, i. e. after the opening of the watertight joint, said wheel 15 moving the pins or bolts 21 by means of a wing 22, (i. e. not by means of a toothed cam 19) provided with a slide 20 for an auxiliary bolt 21. Each auxiliary rut) lid

bolt 21 is connected to the main bolt 21 by a coupling member or link 42. Fig. 5 shows the wing 22 slightly modified in order to indicate more clearly the outer teeth 19 of the toothed wheel 15. For shutting the scuttle port it is only necessary to actuate both shafts 12 and 12 in opposite directions and opposite succession.

It should be noted that the shutting and opening operations are effected in quite a different manner from that employed in the devices or scuttle ports and airtight windows hitherto known and that neither wedges nor inclined planes or parts of screws are used for detaching or for tightening so that turning movements or friction of the tightening parts are entirely avoided.

It will be understood that when the pinion 11 is turned in the reverse direction, i. e. in the direction for shutting the window, the crown 6 carries the pane holder 8 with it through the medium of its collar 7 whilst approaching the frame 2, without turning the pane holder at all. The latter is moved continuously towards the frame 2 in such manner as to remain always parallel to its original position and to the tightening ring 13. The pane holder will thus come into contact with the tightening ring 13 over the whole of its rim at the same time. On continuing to turn the pinion 11 the crown 6 will continue to screw itself on to the projecting rim 3 of the frame 2, thus causing a compression effect, i. e. the pressing of the edge 27 on to the tightening ring 13 without the slightest tendency to rip the watertight packing material. The tightening operation will thus be effected without any disadvantageous action whatever on the parts 13, 27 or 13, 26 which are in contact with one another. It is not possible to apply the controlling devices as shown in Figs. 1 to 5 to all kinds of scuttle ports. For the purpose, however, of rendering it possible in such cases to detach the pane holder 8 properly from its seat in the frame 2 whilst avoiding damage or distortion of the tightening parts, the pane holder may be provided with a flat detaching collar 23 at its rear, i. e. at the side remote from the frame 2, the said collar 23 rendering it possible to detach the pane holder 8, even if it is adhering to the tightening ring 13, over the whole surface at the same time by the employment of any known actuating means.

An example of the application of the invention in this manner is shown in Figs. 7 and 8 which show a scuttle port which can be opened and shut by hand without pinions and toothed wheels. The flat detaching collar 23 is fixed to the back part of the pane holder 8, the latter being actuated by handles 35 rigidly connected to the collar 7, this collar being provided with recesses 25 and projections 24; corresponding to projections 25' and recesses 28 of the frame 2. A groove 36 having inclined planes 37, 38 on both lateral inner surfaces is provided. The inclined planes 37 arranged in front of the recesses 28- serve to detach the pane holder 8. The inclined planes 38 serve to press the pane holder against the watertight ring 13 and are located behind the cams 25. From this it will be understood that by turning the collar? along the inclined surfaces 37 and 38 this collar will be moved away in the direction of its axis, thus detaching the pane holder at the same time along the whole length of the tightening ring 13 or the projecting front edge 27 respectively without the slightest friction.

The pane holder may be adapted to oscillate on its hinge-like joint 39, 40 in order to enable the window to be completely opened, the free space in the front and in the back of hinge pin 39 permitting the pane holder to be detached from the ring 13 and to be moved towards the ring 13 whilst always remaining parallel to said watertight ring without any turing movement taking place along the watertight surfaces 13, 27 in contact with another.
